FERRULE FOR UMBRELLAS OR PARASOLS.

SPECIFICATION forming part of Letters Patent No. 436,251, dated September 9, 1890.

Application filed April 9, 1890. Serial No. 347,178. (No model.)

To all whom it may concern:

Be it known that I, CHARLES EDWARD Marz- GER, of Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Ferrules for Umbrellas or Parasols; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in umbrella-ferrules, the object being to increase the strength and durability of umbrellas or parasols by making substantial connections between the parts; and the invention consists in an elongated ferrule, having a threaded interior and a notched boss at its open end in connection with ribs having fiat balls on their inner ends adapted to enter the notches in the boss, and the umbrella-stick arranged to enter the ferrule and hold the ribs in the notches.

My invention further consists in certain novel features of construction and combinations of parts, as Willbe hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in elevation, showing the ferrule on the umbrella-stick. Fig. 2 is a sectional View through the ferrule. view of the inner end of one of the umbrellaribs, and Fig. 4 is a transverse section.

A represents the ferrule. This is preferably long enough to incase the entire portion of the umbrella-stick, which projects above the cover in order to have an extensive bearing on the stick, and at its extreme end it is provided with a hard-metal tip. An enlargement or bossl is formed at the opposite end of the ferrule, and this portion is provided with equidistant notches 2 2. These notches are in the form of narrow elongated slits 3 3 outside, and inside are in the form of enlarged sockets 4 a with flat walls. The umbrella-ribs 5, one of which is shown in part in Fig. 3, are restricted at the inner ends to form the narrow necks 6 to turn in the slits 3 3, and terminating at the extreme end in the flat balls 7, which fit in the sockets, where they are retained and in which they have bearings. The ribs are kept in the sockets Fig. 3 is a detachedby the stick and the stick is held firmly in the ferrule for a considerable portion of its length by the spiral thead 8 in the interior of the ferrule. This thread forms its own groove in the stick as the latter is screwed into the ferrule. In this manner the stick has an extensive bearing in the ferrule and at the same time it is held rigidly to the ferrule against the balls on the ends of the ribs, holding thelatter in their sockets without the employment of rivet-s or pins, which always weaken the sticks and are forever working loose. As long as the stick is in the ferrule, as described, the ribs are kept in their sockets and it is impossible to remove them without first removing the stick. Then the ribs may be quickly inserted or taken out, and in this way not only the manufacture, but the repair of umbrellas or parasols, is made comparatively easy, and the necessity for repairs is rendered less frequent than heretofore, because those parts which break or rust out easily are dispensed with altogether. It is important to observe in this connection that the slits 3 3 are made of sufficient length to permit the ribs to be raised and lowered to the customary adjustments, and as arranged in the present instance when the umbrella is closed the ribs lie flat against the stick, in this way making it possible to roll the umbrella or parasol into a much smaller roll than heretofore. It may also be observed in this connection that the notches 2 2 are made entirely through the boss to allow the umbrella or parasol to turn inside out without breaking or injuring it in the least. Of course ordinarily it will not do this, but by virtue of this construction it is made possible.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of myinvention, and hence I do not wish to limit myself to the exact construction herein set forth; but

Having fully described my invention, what series of equidistant notches, of ribs having .I claim as new, and desire to secure by Letenlargements adapted to have hearing within the hollow boss, and an umbrella-stick for closing the open inner side of the boss, thereby retaining the ribs in place, substantially as set forth.

The combination, with an umbrella-ferrule consisting of an elongated sleeve having a screw-threaded interior and a hollow boss, the latter being located at the open end of the ferrule, open on its inner side and provided with a series of equidistant notches, of ribs having enlargements adapted to have hearing within the hollow boss, and an 11mbrella-stick screwed into the ferrule and closing the open inner side of the boss, thereby retalilnin g the ribs in place, substantially as set fort 3. The combination, with an umbrella-ferrule consisting of an elongated sleeve hav- CHAS. EDWARD METZGER.
